Long time viewer and reader of the threads here but I just want any possible new ideas or information on the topic. I know a lot of people recommend the mpfi conversion, and I have been needing to put a new spider in. I have been having a misfire code that won’t go away. I did my intake gaskets, both of them, and I had trouble with the poppet for #5. My exhaust somewhat smells like fuel, so I assume it’s the poppet I had trouble with. I did new plugs, wires, and distributor; however I still have a misfire. I’ve changed the plug for #5 since then, and it looked a little wet so I knew it was potentially fouled out. Does anyone recommend a specific brand for the spider? I can’t seem to find any AC-DELCO for sale anywhere, so I was wondering if there was any good potential substitutes for the spider. I’m not looking to go with a cheap, junk brand either. I was wondering if buying from autozone or something similar would be worth it and not a waste of money or time. Any specific recommendations for a good MPFI system to put in my 99 tahoe?
